Subject: bug in select() in linux
Date: Mon, 12 Mar 2007 15:51:19 +0100	[thread overview]
Message-ID: <45219fb00703120751t7acd1ae3kb77f556b81a87634@mail.gmail.com> (raw)

Hello,

I've found a problem in the select() call. The manpage states:
"those in writefds will be watched to see if a write will not block"

I've tried a select() for write against a closed tcp socket (closed by
the other side), and the select call _blocks_.

Any write() call to that socket will _not block_, and will return with EPIPE.

I've seen this happening in 2.4.20 and 2.6.16.29 (xen patched) at least.

Maybe it's a glibc problem - you may know better.

Could you please keep me in carbon copy? I'm not sure I want to
subscribe to LKML.

Regards,
Lluís.
